Ben Bywater
It may not seem like Bywater should be an under the radar player, but fans may forget that the only reason that Bywater played as much as he did last season was because of injuries to Keenan Pili, Chaz Ah You, Max Tooley and Payton Wilgar. By default, Bywater was the only one left standing.
If all of those guys can stay healthy, in some projections Bywater is not even starting. Whether he starts or not, he needs to be big for the defense. If he is not starting, it would be huge for the defense to have a guy come in who will not lower the production on the field. This would help prevent injury and allow guys to stay fresh.
Bywater doesn’t need any particular stats, but he needs to have the kind of season he had last year in being disruptive and effective when on the field.
